That's a crappy characterization of a place, if I've ever heard one. It's a fine place, but nobody thinks "You know, I'm going to become a tech billionaire then live in Austin for the rest of my life." It&#x2

What if an investment fund wanted to buy and hold 20 apartments in a building? That should be illegal in and of itself. People can't afford apartments because "investors" have bought them all to jack up the prices as rent

The "property owned by LLC" issue isn't a _huge_ problem until it's abused. LLC fixes a lot of problems with inheritance and probate, etc. Look at the property records for Woodside (a city zoned _only_ for residential m

you can have four threads compute You could. You could also have a billion threads. But the article is talking about single-core instruction level parallelism where normal tricks like loop unrolling won't work.

First CRC16 is in fact used as a "perfect hash function" It must be implemented by all clients too, so it needs to be simple and readily available. open to an attack by image by a malevolent attacker That wasn't one of th

The constraint was: the output must be CRC-64-Jones, so switching implementations wasn't an option. So, given that constraint, any better solutions are welcome. :)

It exists as well, but isn't mentioned in the article. The article just cares about single process speed-up. The other "merge CRCs" solution starts out resembling: /* Return the CRC-64 of two sequential blocks, where

(i.e. how slow fork is) The problem is fork() is a blocking system call, and the side effects of fork also cause some latency when accessing the COW memory. there should never have to be a full lock of everything. There's no softwa

Arguing about developers not being omnipotent isn't very stable. The users intentionally configured their options and the system responded exactly as it should have, given what it was asked to do.
